Appucation ined June'v 9,

for its object the construction of suchan iin-i plement in which controlling and plowing elements are so located that their operation will-not result in damageto trees of an orchard while permitting a close cultivation.

Referring to the drawingsin which similar numeralsindicate indentical parts- Figure 1 is a plan -view of my improved plow. Figure 2 is a side elevationof Figure 1 showing the plow in operative position.

frame, the front portion of which Vis relatively wide to furnish laterallyspaced bear-` f ing supports for the crank axle on which the.

Figure 3 is a slde elevation of Figure 1 illustrating the plow raised. Figure 4 1s an enlarged fragmentary View `ofthe power liftV mechanism and connected parts. Figure 5 is a detail perspective ofthe forward end of the plow. Figure 6 is a detail view yof part of the rear furrowwheel support and Figure 7 is a' detail of part of the draft device.

vThe main frame comprises a diagonally disposed composite beam formed, preferably, of flat beams or bars 1v and 2 spaced apart and parallel; the beam 2 is bent at 3 to extend forwardly parallel with the line of draft and with a landward frame beam or. bar 4 which, at its rear end, is rigidly connected to the intermediate portion of the diagonal beam. The side members of the frame comprising the bars or beams 2 and4 are bent arched, their forward ends being downwardly, and vthey arey braced firmly apart by an inverted arch bracel or spreader bar 5 bolted to both beams; braces 6 and 7 I thus provide a land and furrow wheels are mounted, as hereinafter described, andthe rear portion of which extends diagonally landward to form a support for the furrow openers.

The wheel system on which the plow vis carried includes alandwheel 8,' a frontfurrowwheel 9 and a rear'furrowwheel 10. 'A crank axle 11 having forwardly directed cranks, extends transversely. of the' frame and is liournaled in a bearing. in a depending bracket l2 securedatan intermediate point on the beam 4, ,the lbearing being sufficiently large to permit forwardand rearward. rocking movement of the axle and also a rocking. movement transversely of` the frame;r Iy

WWMW secureitlie ax1e11frornz longitudinalmovei The landward portion oftheaxle` 11 is v ybent vdownwardly and terminates in a spindle y14 extending under the landward' side of the frame toward the center thereof and on the outer portion ofl which issupporte'd the landwheel 8. The furrowward portion of the axle. 11 islikewise bent downwardly and terminates in an outwardly extending spindle I16 onl which is mounted a furrowwheel 9.

Furrowwardly thewaxle is supported in a.

which is .pivotally mounted, intermediate its length, between thelower end of a bracket 19, bolted to the beam'2, and the lower end of a radius arm 2() of a .notched sectorf2'1 which is rigidly attached to the bracket 19 and to a downwardly projecting extension 22 of auradiusarm 23 of a'notche'd sector 24 secured on the beam 2. A forwardly extending lever 25 is mounted on the pivot of the ward end ofsaid arm by a bolt 26 projecting into any one of a series of holes 27 which are provided in thearm for adjustment of the lever 25 to different positions on the arm 18 to increase or' lessen `its angular relation therewith. It is readily apparent that by operation of the lever 25 the axle 11can be` bearing on a forwardly extending arm. 18

`arm 18 and is adjustably-attached to the forrocked transversely in its bearing onthe beam 4, relatively to the frame to preserve ,the level-.of the plow. The lever 25 is providedwiththe usual type of latch lto engage with the notches in the .sector 21. e

Rig-idly bolted between the beams 1' and 2 are members 28 and 29 which 'form downl ward extensions; ofthe frame, so that with said extensions vand the downturned forward ends of the members 2 and 4 the frame `as, viewed in side elevation presents approxi.- mately the'appearance of anl inverted W, yas y best shown in Fig. 3. To each of the members 28, 29 is secured the standard yof a plowing disk of any suitable type, and'to the member'29is also secured a brackety a composed of parts 30 and 31. The rear furrowwheelf10 is supported on an axle having a vertical spindle 32 journaled in a vertical bearing 33 and extending above the upper end thereof. i Al sleeve 34, preferably` integral with the bearing 33, extends `horizonp tally landward and journaled therein is an arm of a horizontally disposed U-shaped 1 of the lockerea'rm 45 is providedwithan member 35; the remaining arm ofthe memlber 35 is supported in bearings on the part 31 of the bracket a. A link 36 is connected to an eyegin the upper end ofthe vertical;

bearing 33 and extends, iii/,parallelism with the member 35, to connection with an eye in the part 31 of the bracket a. A rod his at.- tached to the member 35 by an eye in one end and extends forwardly Y'at an upward inclination to the member 35 to pass through an openingk in the parts and v31 of the bracketla. A coiled spring i, on the rod 7L,

exerts its force. against the member 30 andl the bracket@ and by expansion assists in raising therear of the plow, and when the plow is loweredthe spring is contracted and so reduces the shock ofthe sudden dropping of the `plow.

An upstanding arm 37 is rigidly attached to the member 35 and has an eye in its upper end in which is hooked an end of a forwardly extending rod'38, said arm with the member 35forming in effect a bell-crank lever. Secured to the landwardk crank arm ofthe axle 1 1 is a casting`39 'having a portion extending rearwardly to which is pivotally attached rearwardlyV extending link 40 the link 40 is bent upwardly at its rear end and through an eye 41 therein the threaded end of the rod'38 extends and is' rigidly and' adjustably securedin place by nuts 42 and 43onopposite sides respectively of the link 40, and by operation of the nuts 42 and 43 longitudinaladjustment of the rod 38 is accomplished to; permit the: rear furrow wheel to run in the saine plane as the discs. The rod 38 and link 40 Ybeing rigidly connected together operate as a single thrust 'rod pivotally attached to the casting 39and to the arm 37, by which construction I avoid using a lost motion connection such as those heretofore used'for a similar purpose employing slots, flexible connections, -or telescoping parts, and provide for positively raising or lowerinoF the rear endofthe frame through the swingingof the arched axle when lit is eye in which is hooked an end of a steering rod 46; the steering rod 46 extends rearwardly to hook engagement witha steeringarm 47 rigidly attached to the upper end lof the spindle 32. Onthe forward termination of the frame beam 4 is mounted, on a horiadjustment Yof the' operatingI zontal pivot, a coupling 48, `and a similar coupling 49 is mounted'in a similar' manner on the beam 2. A draft bar 50 is attached to thepccupling 48 on a vertical pivot, and

is providedw-ith a seriespf holes 51 intermediate its ends; a draft bar 52 is secured to thecoupling 49 in a similar manner and extends diagonally to the draft bar 50 which is composedof parallelifiat bars b and o spaced apart and between which the draft bar 52 is adjustably-lield by a bolt53 passed-through holes in the dra-ft'bar- 50 and anyy one of a series of holesgv54=inQ the draft bar 52.;y

Betweenf'the forward-ends of the bars b andE c" are pivotally secu-red forwardly ex tending `parallel links 55 and'- 56 adapted to"beY attached toa tractor; on the rear portion ofithe link 55 isi-rigidly mounted a furroww-ardly extending ari-n 57, and in the furrowward end of the-arm 57 i-s ahole in'which is'hookedithe'forward endofa rod 58. The

rod 5,8;extends rearwardly, substantially par allel with. the'draft bar 50, and its rear end is'bent horizontallygto an approximate right angleand is journaled in acasting 59secured on aV vertical pivot on the lower end of the rocker arm YBelow the arch brace and extendingbetween the `frame beams 2 and'4, Aand to which it issecured, is a shaft 60on'which is pivotally supported a forH wardly extending arm 61. The armv 61 is formed `of a single flat bar bent upon itself andembraces the rockerarm below the pivotal support-ofthe latter on the bracket 44: The rocker armA 45- is provided with a pin 62 projecting from both sides of the rocker armand engaging with slots 63 in the-r arm 61V and-longitudinal thereof and voperatingas, a stopto contact with either endfofthe'slots 63 and limit the steering movement ofthe wheell'O.

'Theplow is vraised by traction power of the 'landwheel '15 by well-known mechanism which in this inst-ance includes a clutch mountedjon'fthe inner end portion of the landlwheelspindlefsothatit lies approximatelyinidway between the side members ofthe` frame. Consequently the land wheel 'may beset-quite close to the frame, thereby better adapting the plow for use in orchards where it' is necessary to plow close to the trees and itisimportant to avoid damaging them. One of the'lpa-rtsl 64'of the clutch is rigidly attached'fto the hub of the landwheel 8; the second part 65 o f the clutch is looselyT mounted onvthe spindle 14a andhas. preferably integral therewith, a sungear 66. A planetgearf'? meshes with the sun gear 66 and is rigid with. a stub shaft 68 journaled in a bearingfon a member 69. the latter rotatably supported on the spindle 14 adjacent. thev sun gear 166; A link 70 has a bifurcated end embracing the stub shaft 68 and is lsecured1 theretobya pin 71 which passes through the stud shaft and the end ofthe Ylink=; the upper end of the link 70 is piyotally attached to the rear end of an arm 72 which is pivoted intermediate its length on the beam y2 and on the same pivot is supported a lever 73 secured to the forward end of the arm 72 vby a bolt 74 extending through the lever 73 and any one of a series offholes 75 inthe forward end of said arin by'supplying a plurality of holes 75 it isV possible to adjust' the lever 73 to varying degrees of angularity'relative to the arni`72 L f j l -the moment the disks contact with the ground, the lowest pointof the edge of the' andthe frame. lBy'operation of the Alever 73 the depth of plowing is regulated.

A tripping lever 7 (i is pivotally supported,

intermediate its length,l on the end of an arm 77 rigidly mounted on the axle 1l.- On

vthe-opposite side of the arm' 77, and -secured to the arm by the bolt which forms the pivot ofthe tripping lever 76, is'a strap78 parallel withsaid lever, andv between thelower Y ends of the strap 78 rand lever 7 6 is mounted a roller 79 which is adapted to rest upon a dog vv80 to hold'the clutch out of engagement. A relief spring 81 is attached to a lug on the arm 77 adjacent the axle 1l, and extends tothe arch brace 5 to which it isconnected. From the upper end of the tripping lever 76 af rope 83 lead-sto the vtractor within convenient reach ofthe operator, whereby vthe tripping lever 7 6 can be operated to bring intoplay the mechanism just described to rock the axle 1l and raise the plow bythe traction power of the landwheel 8.

The front and rear of the plow are raised simultaneously, for when the` clutch is tripped'into operation and the axle ll rocks and raises the plow, the rod 38, through its connection with the axle 11, is forced rearwardly,` and as it is attached tothe arm 37 on the U-shaped member 35 the latter is rocked 'raising the lrear of the plow, the member 35 operating as a lever-having its fulcrum in the sleeve 34, By this construci tion the parts just vstated are well below the frame levelv and out of the way, and the wheel 10 and its mounting are within thev transverse limit of the structure.

As previously stated the draft bars k50 and 52 are adjustablyA connected for the purpose ofoffsetting the plow from the line of travel of the tractor, the series of holes inv each bar providing forsuch adjust-l ment, and its retention bythe bolt'53. The draft bar 50 andthe'rod 58 aresubstantially parallel, consequently when the plow is offset lfrom the tractor, to operate the" plow close to the trees, the links 55 and 56 are'parallel with the line of advance of the tractor and plow, but if a turn or change in the directionkof travel of the tractor is` made the links 55' and' swingv with the Y pull of thel tractor rocking .the arm 4:5,

, through connection of the rod 58 therewith and with the arm 57 on the link 55'; rocking the arm 4:5 actuatesthe steering rod 46, connected to the steering arm 47 on the spindle 32, consequently the rear furrowwheel The steering rod 46 is made'in two parts Z and e, one telescoping within the other, to provide for any needed adjustment in theI length of the rod, and by means of av set screw f the two parts are held-rigidlyr tol' gether.

`When` the plow is in operation, and from rear disk is in horizontal alinement with a similar point on the wheel 10,. and this aline,

ment is maintained irrespective of the depth ,l0 steers kto follow the turn of the tractor.

of plowing. Thedepth of plowingis regul ground, and if -no previous plowing has been done there is an absence of furrows'- into Ywhich the furrowwheels 9 and l() can travel,

consequently all the wheels and the disks are onthe same level, and asthe landwheel 8 has not completed a revolution to again disf engage the clutch the wheels are free to vrise relativeto the fram'e. As the plow advances the disks gradually seek their predeterf mined depth, which is reached by the time the clutch is disengaged, by which time the Y wheel 8 Vis rotating on the ground surface and the rrear furrowwheel 10 has found thc furrow. The front furrowwheel however alsov travels on the surface unt-il a furrow has been formed inwhich it can travel.

` The link 40 is pivotally connected to the casting 39' intermediate the length of the' landward crank of the axle 11, and to one side thereof, and is rigidly attachedtov the forward end of the rod 38 which is pivotally connected tothe arm 37 of the rear wheel mechanism, so that in the adjustment ofthe Vplow, to a greater or lessy depth than that' shown in Figure 2 of thedrawings, the 'position of the rear furrowwlieel is not affected, because the forward pivot of the link 40' by whichit'is connected to the castingl 39is'in an approximately dead centerA relation to the axis about 'which the axle swings when uthe furrow openers are in operative position, and therefore vertical adjustment of the frame within the range required for depth adjustment does not move the link l0 endwise, since the point of connection of said .link withthe casting 39' then moves practically i-n a vertical line, and consequeiitly it does 'not actuate the lever 37 to raise or lower the rear portion of the frame.

It willbe noted that in the construction of my plow the parts have been so arranged l as to :present alow compact, efficient mechanism, and, as clearly shown in Figure 2, any

parts liable-to cause injuryto lowV hanging loranchesfofan orchard, are either below` the top :level of the frame, or where any parts are ahove thelevel of the frame they arefended by. thesteering rod-46.
